Migrating files to the cloud storage tier

This topic provides a brief description on how to migrate files to the cloud storage tier by using transparent cloud tiering.

Note: Before you try to migrate files to the cloud storage tier, ensure that your cloud service configuration is completed as summarized in Configuring and tuning your system for cloud services.

You can trigger migration of files from your file system to an external cloud storage tier either transparently or manually. Transparent migration is based on the policies that are applied on a file system. Data is automatically moved from the system pool to the configured external storage tier when the system pool reaches a certain threshold level. A file can be automatically migrated to or from cloud storage pool based on some characteristics of the file such as age, size, last access time, path. Alternatively, the user can manually migrate specific files or file sets to a cloud storage pool. For more information on policy-based migration, see Applying a policy on a transparent cloud tiering node.

To manually trigger migration of the file file1, issue this command:

mmcloudgateway files migrate file1

The state of the file becomes Non-resident after it is successfully migrated to the cloud storage tier.

If you want to migrate files in the co-resident state where the file has been copied to the cloud but also allows the data to be retained on the file system, see Pre-migrating files to the cloud storage tier.

For more information on manually migrating files to the cloud storage tier, see mmcloudgateway command command.
